Modifier dynamiquement un spinner
bonjour,
Je souhaite modifier dynamiquement le contenu d'un spinner en fonction d'un autre spinner. Apparement il faut passer par un ArrayAdapter. je me suis inspiré de http://developer.android.com/guide/t...s/spinner.html
Je n'ai pas d'erreur de compilation, mais à l'éxécution j'ai une erreur:
